Answer:
2 litres of water
Step-by-step explanation:
If Ryan drinks 1 1/2 liters of water every 3/4 of an hour at a constant rate, this can also be expressed as;
1 1/2 litres = 3/4 hour
To get the amount of litres Ryan drank for 1 hour
x = 1 hour
Divide both equations
(3/2)/x = (3/4)/1
3/2x = 3/4
2x * 3 = 3 * 4
6x = 12
x = 12/6
x = 2
Hence Ryan drinks 2 litres of water in an hour
